i Application illedJuly, 18H5. Serial No. 172.507. (No model.) i

To all whom 'it may concern.- l. Be it known that I, CHARLES W EINsr'Aorfg of Jersey City, in the county of Hudson 'fand ,l ,State of New Jersey, have invented certain." new anduseful Improvements in Apparatusy *for Cooling Air `for Confectioners Use,

which the following is av speciiicatiomr This invention relates to an ilnproyed paratus 4for cooling air for confection'ers.usel in drying chocolate and other articles ofeon-V fectionery in the summer months; 'and the in-l vention consists of a closed coo1ing-bo`x,within which a system ofpipesis arranged, through which cold water supplied from an ice-water tank is passed. The air is forced in a countercurrent over the cooling-pipes and conducted fro he cooling-box by a distributing-channelto'rfthe-different cooling chambers or cabginets; which. are provided with perforated or other confectionery. An air-forcing apparatus draws the air in a zigza course around g. i, the shelves, and returns the same through a 'suetion-chamberia' suction-pipe to the eooling represents a vermyimproved apg V .oonfectioners and other, purposes. f1 3o Inthe drawing, A represents -a closed and jacketed air-cooling box, which is preferably made of sheet metal and of asize corresponding to the size 'of-the spaces to be cooled.

In the .box A is arranged a cooling-coil or system of cooling-pipes, Bmhich is connected at the upper end bya pipe, B', with an icewater tank, C. The tank C visprovided with a grating or shelf, Cf, forv Supporting the blocks of ice, and with an adjustable overflow-pipe, C, by which the height of water in the tank C can be regulated and the ice be immersedmore or less, whereby the temperature of the water used for cooling-.fthe airis regulated according to the temperature ofthe atmosphere, it being made colder omho't daysand less cold o n cooler days, whereby an average temperature of the air of about o Fahrenheit can be regularly obtained. The water passes from the icc-water tank C to the upper'part of the coil B, then throng the differentA sections of the same, and-is then conducted off. The air is forced by an arr su', ion and forcing appavlower part of the cooling-box A, and then in 'upward ,direction through the box, it being attached to the opposite walls of the coolingratus, D, into the coolingbox A,"and passes first downward in aiside channel, D, to the mpelled to pass in a zigzag course over` the oooling-pipes-B by the action oi' a number ol' horizontal diaphragrms, B, that are alternately 6o box. As the. air passes in a counter-current to that of the water through the cooling-box A, it is gradually brought in contact with colder pipe-sections until it reaches, nal'ly, the coldest pipe-sections lat the upper part/.of

thc box A. From the upper part of the cooling-box the air is passed through a channel, D'Z, at the opposite side of the same, to a rcceiving-chamber, F. 'A drip-pan, E, is arranged at the bottomo the cooling-box A, for collecting the water of condensation that is deposited by the air on the surface of the cooling-pipes. The receiving-chamber F extends from the lower part of the air-cooling box A to the bottom of refrigerating chambers or 'cabinets l ",'and communicates therewith by 'means of valved openings ff. The articles to be dried are placed on trays, which are supported on shelves F2, that' are alternately attached to opposite side wallsof-the cabinets 8o F. The shelves F are perforated or made of vwire, to admit the, direct passage-of the air through the shelves! when the trays are removed, while whenthe trays are-in position the air is forced in ai'zigzag course around the shelves and trays, as shownI by arrows in the drawing. The upper part of thecabin'ets Ff communicate by short pipes f with a suctionchamber, G, that extends over the top ofthe cabinets, and that is connected by a suctionpipe, G', to the fan 'orother air-forcing apparatus D, which is preferably supported at the top part of the air-coolng'gfboxy A. By the air-forcing apparatus the .airis passed iu a continuous circuit froni-the'cooling-bor;v to the cabinets,and from the cabinets bakto the vcooling-box. The moisture that is evaporated 'by the confectionery is carried al( ng by the the cooling coil,-

ternately from opposite walls, a coil or system ery placed therein without discoloring the same oi forming a film on the surface of the same. The chocolate or other confectionery retains thereby its natural color and .assumes a permanent solid state. The temperature of the cooling-Water is regulated according to the temperature of the atmosphere, icc-water I beingl used in hot weather, While in cooler i Weather Well-Water of ordinary temperature i may be used Afor cooling purposes. Having thus described myinvention, I claim i as new and desire to secure by Letters latent--- i 1. The combination of a closed air-cooling box, ,lin the same, a cold-water tank connected 'to a number of refrigerating chambers or cabinets, an air-forcing apparatus, a distributing-chamber connecting the coolingbox with the cabinets, and channels for connecting the air-'forcing apparatus with the cooling-box and the drying-chambers, substantially asset forth.

-2. The combination of a closed air-cooling box having interior diaphragms extending alphragms, a cold-Water tank connected with of pipes located in said box between said diasaid system vof pipes, an air-forcing apparatus, i

a coil or system of cooling-pipes located Water tank having a grating or shelf for the for cooling air, a closed air-cooling box having an interior coil or system of pipes, a drip-pan at the bottom of the same, and alternately-arranged -diaphragms for conducting the air ina cireuitons course over the pipes, substantially asset forth.

4. In anapparatus for cooling air, a coldice and an adjustablel overfiow-pipe. substantially as set forth.

5. In an apparatus for cooling air, a refrigeratingchamber or cabinet having perforated or wire shelves attached alternately to the opposite side walls, substantially as set forth.

invention I have signed'my name in of two subscribing witnesses.
